Crimewatch is a long-running and high-profile British television programme produced by the BBC, that reconstructs major unsolved crimes with a view to gaining information from the members of the public. The programme was originally broadcast once a month on BBC One, although in more recent years the programme has more usually been broadcast roughly once every two months. It was announced on 15 October 2008, that the BBC is to move the filming of shows such as Crimewatch to studios in Cardiff. The show was first broadcast on 7 June 1984, and is based on the German TV show Aktenzeichen XY … ungelöst. It was first presented by Nick Ross and Sue Cook. When Cook left in 1995, she was replaced by Jill Dando. After Dando's murder in April 1999, Fiona Bruce took over. Kirsty Young, Matthew Amroliwala and Martin Bayfield currently front the show; following the departures of Ross and Bruce in 2007 and Rav Wilding on 15 December 2011.
